I just tried playing ff 13-2 a couple of times and every so often a window would pop up saying that the save device containing the dlc I was using was disonnected, and then it relaunches the the game. The dlc in question is the genji bow and summoner's garb costume for serah, which are the preorder bonuses. This issue has occured with my flash stick, the 'memory unit' that's built in to the console, one of the slim consoles, and also the 250gb hard drive bought and inserted, and all while I'm not even thouching the console. Also it happened just when I was watching the openeing cutscene movie, not even touching the controller. how can i resolve this issue?
